DESCRIPTION
The DG2302 is a high-speed, 1-bit, low power,
TTL-compatible bus switch. Using sub-micron CMOS
technology, DG2302 achieves low on-resistance and
negligible propagation delay.
The DG2302 consist of a bi-directional input/output pins A and
B. When the output enable (OE) is low, the input/output pins
are connected. When the OE is high, the switch is open and
a high-impedance state exists between input/output pins A
and B.

Notes:
a. Room = 25°C, Full = as determined by the operating suffix.
b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
c. Typical values are for design aid only, not guaranteed nor subject to production testing.
d. Guarantee by design, nor subjected to production test.
e. VIN = input voltage to perform proper function.
f. Guaranteed by design and not production tested. The bus switch propagation delay is a function of the RC time constant contributed by the on-resistance and
the specified load capacitance with an ideal voltage source (zero output impedance) driving the switch.
